Hey bud. I took delivery of the truck in Jan. of '11. It was Nov.- Dec. when I bought the Stainless Works system. The dealership were I ordered the truck did the install. It's been nearly 2 1/2 years and no issues, leaks, squeeks since then. No, I didn't have to have the trucks computer redone. The performance increase was immediate, and awesome! It really didn't start coming alive until a few days later. I could feel the performance getting better and shifting better each day. I guess it relearns on it's own. I take the truck to the dealer for oil changes. I have Free Oil Changes for as long as I own the truck. Sorry I can't help you there. Why did you let the Ecoboost go? I ordered my Lariat in Oct. '10. I never even thought about the Ecoboost. When I learned that the 6.2 would be available in other F150's besides the Raptor, the 6.2 was a Must Have on the special order ticket. I know your gonna enjoy your truck, even in stock form she's a beast......

Hi Scarlet, I noticed your modifications to your 6.2L and I'm impressed with your results so far. I recently upgraded my EB to a 6.2L as well and interested in doing something similar as you. Regarding your headers, did you have your vehicle retuned afterwards or just had the computer reset to relearn everything? Lastly, what oil brand are you using? Thanks for the info.
